Description

Technical Field

[0001] The present invention relates to the technical field of connection of prefabricated curtain wall profiles, and specifically to a modular connection system and installation process for prefabricated curtain wall profiles. Background Technique

[0002] With the acceleration of the urbanization process, the number of high-rise buildings and buildings with complex shapes has increased year by year. As an important part of the building's exterior envelope structure, the installation efficiency and structural safety of building curtain walls directly affect the project cycle and service reliability.

[0003] However, in the prior art, the connection between the curtain wall profiles of the traditional curtain wall connection system and the main structure, and between the profiles and the panels mainly relies on on-site welding, bolt-by-bolt fixing and other processes, which have the problems of cumbersome procedures, high risk of high-altitude operations, and structural stress concentration, resulting in low construction efficiency, longer single-module installation time compared with prefabricated assembly processes, increased resource investment, and increased labor costs; at the same time, there are defects in structural performance and durability, and the local tensile strength in the heat-affected zone of welding will decrease, resulting in obstacles to the transformation of building industrialization, too low prefabricated assembly rate, and it is difficult to meet the development trend of modern building industrialization and assembly. Summary of the Invention

[0004] The purpose of the present invention is to provide a modular connection system and installation process for prefabricated curtain wall profiles to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A modular connection system for prefabricated curtain wall profiles includes a pre-embedded part, a connection mechanism is fixedly connected to the side of the pre-embedded part, an adjustment mechanism is installed on the side of the connection mechanism, an installation base is fixedly connected to the upper part of the adjustment mechanism, and the pre-embedded part, the connection mechanism, the adjustment mechanism and the installation base form the main body of the connection system. The connection mechanism includes a connection plate and an installation frame. A plug is fixedly connected to the side of the connection plate, the plug is inserted into the surface of the pre-embedded part, and the installation frame is fixedly connected to the connection plate; The adjustment mechanism includes a strip-shaped slide rail and an adjustment bolt. The strip-shaped slide rail is fixedly connected to the side of the installation frame, and a strip-shaped slide block is slidably connected inside the strip-shaped slide rail. One end of the adjustment bolt is rotatably connected to the side of the strip-shaped slide block, and the adjustment bolt is threadedly connected to the strip-shaped slide rail. A fixing plate is fixedly connected to the side of the strip-shaped slide block, and an adjustment shaft is rotatably connected to the surface of the fixing plate. The top of the adjustment shaft is fixedly connected to the installation base, and a locking bolt is threadedly connected to the bottom of the fixing plate, and the end of the locking bolt is pressed and fixed to the side of the adjustment shaft.

[0006] Preferably, the plug is obliquely arranged on the side of the connection plate, a limiting groove adapted to the plug is arranged on the surface of the pre-embedded part, and the plug is located inside the limiting groove and is inserted into the pre-embedded part.

[0007] Preferably, the connection plate and the pre-embedded part are fixedly connected by connection bolts.

[0008] Preferably, a limiting rod is fixedly connected to the end of the strip-shaped slider, and a spring is arranged on the surface of the limiting rod. One end of the spring is fixedly connected to the strip-shaped slider, and the other end of the spring is fixedly connected to the inside of the strip-shaped slide rail.

[0009] Preferably, an arc-shaped slide rail is fixedly connected to the upper part of the fixing plate, an arc-shaped slider is slidably connected inside the arc-shaped slide rail, and the arc-shaped slider is fixedly connected to the bottom of the mounting base.

[0010] In the present invention, by rotating the adjusting bolt to push the strip-shaped slider to slide inside the strip-shaped slide rail, the horizontal position of the mounting base is accurately adjusted. During the process of the strip-shaped slider sliding along the strip-shaped slide rail, the limiting rod will slide along the strip-shaped slide rail to perform secondary limiting on the sliding of the strip-shaped slider, improving the stability of the strip-shaped slider during movement. At the same time, the spring will generate a compressive or tensile deformation, and the elastic force generated by the spring will generate a certain prestress at the threaded connection between the adjusting bolt and the strip-shaped slide rail, so as to keep the adjusting bolt and the strip-shaped slide rail stable, and further keep the mounting base in a stable position during the process of connecting and fixing with the curtain wall panel.

[0011] By rotating the adjusting bolt to push the strip-shaped slider to slide inside the strip-shaped slide rail, the horizontal position of the mounting base is accurately adjusted. During the process of the strip-shaped slider sliding along the strip-shaped slide rail, the limiting rod will slide along the strip-shaped slide rail to perform secondary limiting on the sliding of the strip-shaped slider, improving the stability of the strip-shaped slider during movement. At the same time, the spring will generate a compressive or tensile deformation, and the elastic force generated by the spring will generate a certain prestress at the threaded connection between the adjusting bolt and the strip-shaped slide rail, so as to keep the adjusting bolt and the strip-shaped slide rail stable, and further keep the mounting base in a stable position during the process of connecting and fixing with the curtain wall panel; Then rotate the adjusting shaft to accurately adjust the horizontal angle of the mounting base. At this time, the arc-shaped slider slides along the arc-shaped slide rail to limit the mounting base during the process of angle adjustment, improving the stability of the mounting base during angle adjustment. After the angle adjustment of the mounting base is completed, tighten the locking bolt to lock and fix the adjusting shaft to the bottom of the fixing plate to ensure that the angle of the mounting base remains unchanged; finally install the curtain wall panel, embed an elastic rubber strip in the splicing seam of the curtain wall panel, and inject silicone sealant externally.

[0012] An assembled curtain wall profile modular installation process includes the following steps S1. Use building information modeling for module parametric design to generate processing drawings, and complete module assembly in the factory: pre-install and fix the connection mechanism, adjustment mechanism, and mounting base; S2. Use a laser total station to locate the installation position of the embedded parts on the building surface, and embed the embedded parts at the set position; S3. The installer carries the pre-assembled connection mechanism, adjustment mechanism and installation base, inserts the insertion block on the side of the connection plate into the embedded part, and then fixes the connection plate and the embedded part with connection bolts; S4. By rotating the adjustment bolt to push the strip-shaped slider to slide inside the strip-shaped slide rail, the horizontal position of the installation base is accurately adjusted, and then the adjustment shaft is rotated to accurately adjust the horizontal angle of the installation base; S5. Finally, install the curtain wall panel, embed an elastic rubber strip in the splicing seam of the curtain wall panel, and inject silicone sealant externally.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the installer carries the pre-assembled connection mechanism, adjustment mechanism and installation base assembly, inserts the insertion block on the side of the connection plate into the embedded part, which is convenient for quickly connecting and fixing the pre-installed components and the embedded part. By inserting the insertion block into the embedded part, an effective support structure is formed, reducing the stress on the fixed part of the embedded part and the connection plate by the connection bolt, improving the stability of the connection between the embedded part and the connection mechanism. The inclined design of the insertion block causes a self-locking effect on the insertion interface. When bearing a horizontal load, the contact surface between the insertion block and the limit groove forms a reaction force perpendicular to the load direction, improving the uplift resistance. At the same time, the insertion block bears the horizontal shear force and vertical load, so that the connection bolt only needs to bear the remaining load, reducing the stress concentration phenomenon around the bolt hole. The blind insertion docking of the insertion block and the limit groove shortens the single-node connection time, especially suitable for high-altitude operation scenarios.

[0014] 2. In the present invention, horizontally, the adjustment bolt pushes the strip-shaped slider to slide along the slide rail, and with the secondary limit of the limit rod and the spring prestress compensation, the accuracy of horizontal adjustment is guaranteed. During angle adjustment, the arc-shaped slider slides along the arc-shaped slide rail for guidance, and the adjustment shaft cooperates with the locking bolt to achieve stepless precise positioning, avoiding the problems of jamming and loosening in traditional angle adjustment, significantly improving the adjustment accuracy, structural stability and sealing performance of curtain wall installation. At the same time, the construction process is simplified, effectively reducing the errors of high-altitude operations and the later maintenance cost, and is applicable to the high-precision curtain wall installation requirements of complex-shaped buildings.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Example 1: Refer to Figures 1-5 As shown: A modular connection system for an assembled curtain wall profile includes an embedded part 2. A connection mechanism 3 is fixedly connected to the side of the embedded part 2. An adjusting mechanism 4 is installed on the side of the connection mechanism 3. An installation base 5 is fixedly connected to the upper part of the adjusting mechanism 4. The embedded part 2, the connection mechanism 3, the adjusting mechanism 4, and the installation base 5 form the main body 1 of the connection system. The connection mechanism 3 includes a connection plate 31 and an installation frame 32. An insert block 34 is fixedly connected to the side of the connection plate 31. The insert block 34 is inserted into the surface of the embedded part 2. The installation frame 32 is fixedly connected to the connection plate 31. The insert block 34 is inclined on the side of the connection plate 31. A limiting groove adapted to the insert block 34 is provided on the surface of the embedded part 2. The insert block 34 is located inside the limiting groove and is inserted into the embedded part 2.

[0019] In this embodiment, building information modeling is used for modular parametric design to generate processing drawings, and then the connection mechanism 3, the adjusting mechanism 4, and the installation base 5 are pre-installed and fixed; A laser total station is used to position the installation position of the embedded part 2 on the building surface, and the embedded part 2 is embedded at the set position to ensure the accurate installation position of the embedded part 2; The installer carries the pre-assembled connecting mechanism 3, adjusting mechanism 4 and mounting base 5 components, and inserts them into the embedded part 2 through the insertion block 34 on the side of the connecting plate 31, which facilitates the quick connection and fixation of the pre-installed components and the embedded part 2. By inserting the insertion block 34 into the interior of the embedded part 2, an effective support structure is formed, reducing the stress on the fixed part of the embedded part 2 and the connecting plate 31 by the connecting bolt 33, and enhancing the stability of the connection between the embedded part 2 and the connecting mechanism 3.

[0020] Due to the inclined design of the insertion block 34, a self-locking effect is generated at the insertion interface. When a horizontal load is applied, the contact surface between the insertion block 34 and the limit groove forms a reaction force perpendicular to the direction of the load, enhancing the uplift resistance. At the same time, the insertion block 34 bears the horizontal shear force and vertical load, enabling the connecting bolt 33 to only bear the remaining load, reducing the stress concentration phenomenon around the bolt hole. The blind insertion docking of the insertion block 34 and the limit groove shortens the single-node connection time, especially suitable for high-altitude operation scenarios.

[0021] Example 2: According to Figures 1-5 As shown, the connecting plate 31 and the embedded part 2 are fixedly connected by a connecting bolt 33. A limit rod 49 is fixedly connected to the end of the strip-shaped slider 42, and a spring 410 is arranged on the surface of the limit rod 49. One end of the spring 410 is fixedly connected to the strip-shaped slider 42, and the other end of the spring 410 is fixedly connected to the interior of the strip-shaped slide rail 41. An arc-shaped slide rail 45 is fixedly connected to the upper part of the fixing plate 44, and an arc-shaped slider 46 is slidably connected to the interior of the arc-shaped slide rail 45. The arc-shaped slider 46 is fixedly connected to the bottom of the mounting base 5. The adjusting mechanism 4 includes a strip-shaped slide rail 41 and an adjusting bolt 43. The strip-shaped slide rail 41 is fixedly connected to the side of the mounting frame 32, and a strip-shaped slider 42 is slidably connected to the interior of the strip-shaped slide rail 41. One end of the adjusting bolt 43 is rotatably connected to the side of the strip-shaped slider 42, and the adjusting bolt 43 is threadedly connected to the strip-shaped slide rail 41. A fixing plate 44 is fixedly connected to the side of the strip-shaped slider 42, and an adjusting shaft 47 is rotatably connected to the surface of the fixing plate 44. The top of the adjusting shaft 47 is fixedly connected to the mounting base 5. A locking bolt 48 is threadedly connected to the bottom of the fixing plate 44, and the end of the locking bolt 48 is squeezed and fixed to the side of the adjusting shaft 47.

[0022] In this embodiment, by rotating the adjusting bolt 43, the strip-shaped slider 42 is pushed to slide inside the strip-shaped slide rail 41 to precisely adjust the horizontal position of the mounting base 5. During the sliding of the strip-shaped slider 42 along the strip-shaped slide rail 41, the limit rod 49 will slide along the strip-shaped slide rail 41 to further limit the sliding of the strip-shaped slider 42, enhancing the stability of the movement of the strip-shaped slider 42. At the same time, the spring 410 will undergo compression or stretching deformation, and the elastic force generated by the spring 410 causes a certain prestress at the threaded connection between the adjusting bolt 43 and the strip-shaped slide rail 41, thereby keeping the adjusting bolt 43 and the strip-shaped slide rail 41 stable. Furthermore, during the connection and fixation of the mounting base 5 to the curtain wall panel, the position is always kept stable. Then rotate the adjustment shaft 47 to precisely adjust the horizontal angle of the mounting base 5. At this time, the arc-shaped slider 46 slides along the arc-shaped slide rail 45 to limit the mounting base 5 during the angle adjustment process, improving the stability of the mounting base 5 during angle adjustment. After the angle adjustment of the mounting base 5 is completed, tighten the locking bolt 48 to lock and fix the adjustment shaft 47 to the bottom of the fixing plate 44 to ensure that the angle of the mounting base 5 remains unchanged. Finally, install the curtain wall panel, embed an elastic rubber strip in the joint of the curtain wall panel, and inject silicone sealant externally.

[0023] In the horizontal direction, the adjustment bolt 43 pushes the strip-shaped slider 42 to slide along the slide rail, and cooperates with the secondary limit of the limit rod 49 and the prestress compensation of the spring 410 to ensure the accuracy of horizontal adjustment. During angle adjustment, the arc-shaped slider 46 slides along the arc-shaped slide rail 45 for guidance, and the adjustment shaft 47 cooperates with the locking bolt 48 to achieve stepless precise positioning, avoiding the problems of jamming and loosening in traditional angle adjustment, significantly improving the adjustment accuracy, structural stability and sealing performance of curtain wall installation. At the same time, it simplifies the construction process, effectively reduces the errors of high-altitude operations and the later maintenance cost, and is suitable for the high-precision curtain wall installation requirements of buildings with complex shapes.

[0024] Embodiment 3: According to Figure 5 As shown, an assembled curtain wall profile modular installation process includes the following steps: S1. Use the building information model for module parametric design to generate processing drawings, and complete module assembly in the factory: pre-install and fix the connection mechanism 3, the adjustment mechanism 4 and the mounting base 5. S2. Use a laser total station to position the embedded part 2 on the surface of the building, and embed the embedded part 2 at the set position. S3. The installer carries the pre-assembled connection mechanism 3, adjustment mechanism 4 and mounting base 5, inserts the plug 34 on the side of the connecting plate 31 into the embedded part 2, and then fixes the connecting plate 31 and the embedded part 2 with the connecting bolt 33. S4. Push the strip-shaped slider 42 to slide inside the strip-shaped slide rail 41 by rotating the adjustment bolt 43 to precisely adjust the horizontal position of the mounting base 5, and then rotate the adjustment shaft 47 to precisely adjust the horizontal angle of the mounting base 5. S5. Finally, install the curtain wall panel, embed an elastic rubber strip in the joint of the curtain wall panel, and inject silicone sealant externally.

[0025] The usage method and working principle of this device: Use the building information model for module parametric design to generate processing drawings, and then pre-install and fix the connection mechanism 3, the adjustment mechanism 4 and the mounting base 5. Use a laser total station to locate the installation position of the embedded part 2 on the building surface, and embed the embedded part 2 at the set position to ensure the accurate installation position of the embedded part 2; The installer carries the pre-assembled connecting mechanism 3, adjusting mechanism 4 and installation base 5 components, and inserts them into the embedded part 2 through the insertion block 34 on the side of the connecting plate 31, which is convenient for quickly connecting and fixing the pre-installed components and the embedded part 2. By inserting the insertion block 34 into the embedded part 2, an effective support structure is formed, reducing the stress on the fixed parts of the embedded part 2 and the connecting plate 31 by the connecting bolt 33, and improving the stability of the connection between the embedded part 2 and the connecting mechanism 3; By rotating the adjusting bolt 43 to push the strip-shaped slider 42 to slide inside the strip-shaped slide rail 41, the horizontal position of the installation base 5 is accurately adjusted. During the sliding of the strip-shaped slider 42 along the strip-shaped slide rail 41, the limiting rod 49 will slide along the strip-shaped slide rail 41 to limit the sliding of the strip-shaped slider 42 again, improving the stability of the movement of the strip-shaped slider 42. At the same time, the spring 410 will produce a compressive or tensile deformation, and the elastic force generated by the spring 410 will generate a certain prestress at the threaded connection between the adjusting bolt 43 and the strip-shaped slide rail 41, so that the adjusting bolt 43 and the strip-shaped slide rail 41 are kept stable, and then the installation base 5 always maintains a stable position during the connection and fixation with the curtain wall panel; Then rotate the adjusting shaft 47 to accurately adjust the horizontal angle of the installation base 5. At this time, the arc-shaped slider 46 slides along the arc-shaped slide rail 45 to limit the installation base 5 during the angle adjustment, improving the stability of the angle adjustment of the installation base 5. After the angle adjustment of the installation base 5 is completed, tighten the locking bolt 48 to lock and fix the adjusting shaft 47 to the bottom of the fixing plate 44 to ensure that the angle of the installation base 5 remains unchanged; Finally, install the curtain wall panel, embed an elastic rubber strip in the splicing seam of the curtain wall panel, and inject silicone sealant externally.
